A VERY efficient type of traction, originally used by Hoke and known as the "Hoke-Martin Plaster Traction,"1 is often overlooked when strong fixed traction is desired. As originally described, a plaster hip spica is applied extending from the nipple line down to and incorporating the foot on the well side and down to just above the knee or to the lower part of the leg on the affected side. Two metal bars, joined at the end and between which a ratchet is placed 2 in. (5 cm.) from the end, are incorporated into the plaster on the affected side. Either skeletal traction or skin traction can be applied to the extremity, above or below the knee as required.

Herein is described a modification of the apparatus which is very useful in conditions such as old or "irreducible" congenital dislocation of the hip, old fracture dislocations, when it is desired
